A process for joining bristle bundles to a plastic bristle carrier, wherein the bristles of each bundle are melted at their fastening-side ends, accompanied by the formation of a thickened portion. The bristle carrier is provided at the bristle reception side with holes for receiving the thickened portions. The bristle bundles with the thickened portions are pressed into the bristle carrier, with a space above a bristle receiving side and between the bristle bundles, annularly surrounding the bristle area, being sealed against the bristle carrier, and with material rising during pressing on pressure application and filling the sealed area being displaced and compressed.
